(CNN) - A federal judge in Utah has struck down the state's ban on same-sex marriage, saying the law "conflicts with the United States Constitution's guarantees of equal protection and due process under the law."

In striking down the state law, which voters approved in 2004, the judge ruled that the state's "current laws deny its gay and lesbian citizens their fundamental right to marry and, in so doing, demean the dignity of these same-sex couples for no rational reason.
